Engineering the Assembly Freedom of Donor–Acceptor Type Self‐Assembled Monolayers Toward Efficient and Stable Flexible Perovskite Photovoltaics

open access: yesAdvanced Materials, EarlyView.
Assembly freedom engineering breaks the vertical alignment constraint of donor–acceptor self‐assembled monolayers, tuning their assembly freedom to achieve quasi‐random molecular orientation. This strategy simultaneously boosts interfacial charge transport and mechanical robustness, enabling high‐efficiency and mechanically stable flexible perovskite ...

Study on High-Temperature, Ultra-Low Wear Behaviors of Ti6Al4V Alloy with Thermal Oxidation Treatment

open access: yesCoatings
Thermal oxidation (TO) is a simple and economical way to enhance the wear resistance of the Ti6Al4V alloy. The TO temperature has a very important effect on the tribological properties of the TiO2 layer formed. However, the impact of the oxidation temperature on the high-temperature tribological behavior of a TO-treated Ti6Al4V alloy is not clear ...
